Let's talk about the end dimension...

Unlike the nether, which is entirely fine as it is, the end dimension is in need of a huge makeover. The end dimension is in need of more life, whether pretty dangerous or not and more rare structures containing even better loot. The end dimension is also in need of more ores that will be rarer and stronger than Netherite, and speaking of Netherite, Netherite armor should make you fire resistant just like Netherite itself because it's fire resistance is one of the most noticeable feature about it
